30 vs 40 vs 50 yr warranty

I'm in the NW where it rains alot...and got bids for 30,40,50 yr . Ultimately HOW long will these composite roofs really last?
Yes I understand the 50 is supposed to be asthetically pleaseing which i really dont care but will the 50yr really last 10 yrs longer than 40 or even 20 yrs longer than the 30?
what really does the warranty mean?
THANKS!!!

Most are on steep slope roofs and that really adds to the life of any roof so that kind of skews the curve a bit.
Like Ed says it all depends on the installation. A roof put on wrong is not going to last as long as one put on properly. In installation as well as material, you get what you pay for. Cheaper is not better in the long run.

Assuming this is just the cost of materials30yr = $5495 = $180/yr of life40yr = $5795 = $145/yr of life50yr = $6019 = $120/yr of life

So, best deal for you seems to be the 50 yr.

But, if hardly anyone makes warranty claims (even if they find the contract after so many years) the best deal for the company is to use the lowest quality shingle for the highest price, let's say, 90% of the time, and this percentage is adjusted slightly up or down depending on business conditions. In the unlikely event that they are caught they can say it was a factory mixup (oops!).

What you might do is get several bids and plot the dollars/yr of life along a line. If there is a cluster in the middle, this is probably the true cost/yr of life for shingles.E.g., x xxx x$0 $100 $200 $300

(turns out I can't plot this line, so imagine the first x is over 100, the next three are over 200 and the last x is over 300).

So for 30 yr shingles, company A comes in at $100/yr of life, company B at $300/yr of life, and three others are all clustered around $150 to $200/yr of life. So company A is importing shingles from somewhere and company B is gouging. The rest are all bidding on the same job.

Even if 10 years more were the proper amount of additional years, that works out to only $25.00 per year, or $2.085 per month.

If the job is done correctly, the shingles WILL have their proper life cycle.

Properly also means addressing the Intake Ventilation as well as the Exhaust Ventilation.

Now, figure it out, which one will provide the lowest cost cycle per month or per year for only a measly few extra hundred bucks.

OK OK... THANK YOU ED!!!
If i put that measly few hundred bucks in an IRA @ 6% for 20 yrs it'd become $1820. BUt then - who's to say i'll get 6%??? who's to say if i'd get 20 yrs more? ANYWAY..I get your point and as you say - key is proper installation & ventillation for the ultimate durations in the shingles.
